Abstract:
Objective To provide technical support for developing portable and carrying PSA medical oxygen generators under variable altitudes. Methods Based on the operation principle of PSA technology, the effects of altitude on the performance capacity of series of PSA medical oxygen generators were analyzed. PSA oxygen generating technology was explored with an inlet system with variable frequencies and constant pressure. The problems due to the introduction of the converter were discussed during studying key technologies, and some countermeasures were put forward accordingly. Trials were executed with 1.2 Nm3/h generator taken as an example. Results The PSA medical oxygen generator developed met the requirements of corresponding standards of medical molecular sieve oxygen generator at the altitudes from 0 to 4451 m. Conclusion The PSA oxygen generator has its adaption altitude enhanced significantly.
